V
VBR
Variable Bit Rate. A type of ATM
traffic flow. As opposed to
Constant or Continuous Bit

VC Multiplexing
An older protocol that allows
you to connect ATM nodes using
PVCs (also known as null
encapsulation).
VCC
Virtual Channel Connection. A

between two endpoints where
higher layer protocols are
accessed. By definition, ATM cell
sequence must be preserved
over a VCC.
VCI/VPI
Virtual Channel Identifier/
Virtual Path Identifier. ATM
addressing information. An
identifying value found in the
header of each ATM cell.
VLAN
Virtual LAN. A logical collection
of member endpoints and
network devices grouped
together in secure, autonomous
domain. Membership in a
VLAN is not restricted by
physical location. VLANs in
ATM networks may be built
upon emulated LANs.
VPC
Virtual Path Connection. A
joining of virtual path links
between two points in which the
VCI values are either reassigned
or terminated. Several VCCs
may be bundled into one VPC.
W
